NY Loc. 3 - Gardiners Island (Pleistocene of the United States)

Where: Suffolk County, New York (41.1° N, 72.1° W: paleocoordinates 41.1° N, 72.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• STRATIGRAPHIC RELATIONS: no stratigraphic data reported in text, Gardiners Clay and Jacob Sand according to Richards (1962). Jacobs Sand (Sangamon-Wisconsin) overlies the Gardiners Clay (Sangamon). AGE: Sangamon (MacClintock and Richards 1962), Pleistocene (Richards 1962).

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified claystone and sandstone

• DEPTH: no specific data, apparently, shallow shelfal fauna. SALINITY: no specific data, apparently normal marine. THERMAL TOLERANCES: no specific data, apparently temperate fauna. PALEOBIOGEOGRAPHY: no specific data, apparently normal northern coastal plain assemblage.
• SPECIFIC LITHOLOGY: no lithologic data reported in Clark (1906), claystone and sand according to Richards (1962). LITHIFICATION: Assumed to be unlithified based on age and figured specimens in Richards (1962).

Collection methods: quarrying,

• SOURCE: List compiled from earlier lists based on earlier collections. COLLECTOR: Packard (1865), Verrill (1875), Fuller (1914), MacClintock andf Richards (1936). REPOSITORIES: Collections held in various museums, possibly including the Academy of Natural Sciences, USNM, MCZ (Cambridge), and AMNH.
